engineering plans for construction of improvements, promotes
uniform traffic engineering practices standards, and policies
statewide, and provides administrative services. This Group
is subdivided into three units and a stenographic pool, as
shown below.
The Traffic Control Unit prepares traffic control plans for
contract construction and maintenance projects involving
construction phasing, construction methods, and traffic
control devices to safely and efficiently handle traffic in
work zones. This unit is also responsible for pavement
marking
.
The S ignals and Geometries Unit prepares traffic and
geometric design plans for Spot Safety improvements and
traffic signal designs for contract installation. This unit
also coordinates the preparation of agreements and plans for
the installation of railroad-grade crossing signals.
The Signing Unit prepares sign design plans (including sign
lighting) for contract construction projects, and reviews
requisitions for signs and sign materials installed by
Division Traffic Services.
The Stenographic Pool is responsible for all clerical and
centralized word processing for the Branch. The Pool is also
responsible for processing purchase requisitions, securing

Management Unit, Traffic Studies Unit, five Area Traffic
Engineering Units located in Wilson, Durham, Fayetteville
,
Winston-Salem, and Asheville, and a Field Support Squad.
The Signals Management Unit optimizes the timing and
operation of traffic signals and signal systems, and prepares
traffic signal specifications. This unit also is involved in
the inspection of traffic signal and railroad crossing signal
installations. This unit also operates a signal repair shop
located in Raleigh.
The Traffic Studies Unit serves as a liaison between the
field units, the technical operations function, other
branches within the Division of Highways, various state and
federal agencies and the public in general. This unit
reviews roadway plans in the preliminary and advanced stages
of design; and reviews driveway permits for major traffic
generating locations. Other duties include performing
special traffic engineering projects, conducting evaluations
on traffic control devices, maintaining the branch technical
library, coordinating technical meetings and training
activities, and publishing technical materials.
Each Area Traffic Engineering Unit has two traffic engineers
who investigate and recommend improvements at locations on
the State Highway System which are experiencing traffic
operational and safety problems, including locations
identified on the various Highway Safety programs. The five
Area Traffic Engineers work closely with the 14 Division
Traffic Engineers located throughout the State (see map, page
6, "Area Traffic Engineering Unit Area Assignments"),
providing technical advice, interpretation of policy, and
technical assistance.

TRAFFIC CONTROL UNiT
Purpose
:
This unit was formed in the late 1970 's in direct response to
Federal Highway Notice N-5000.7, which requires all highway
construction projects involving Federal Highway Funds have a
Traffic Control Plan (TCP) to protect workers and safely
guide motorists thru a roadway construction workzone . As an
extension of this directive, the North Carolina Department of
Transportation also requires a TCP plan for all State-Funded
roadway construction projects. Secondary responsibilities of
the Traffic Control Unit include developing Roadway Pavement
Marking and Delineation plans for all Federally and State
Funded roadway construction projects to safely guide
motorists along the North Carolina system; providing
guidance, standards, and policies on Traffic Control, Roadway
Pavement Marking, and Delineation Plans to all other branches
of the Division of Highways, Departments of State Government,
Municipalities, Utility Companies, and private engineering
firms pertaining to any work being performed in the highway
right-of-way.

-10-
... A series of Traffic Control Unit Training classes to make
all plan design concepts more consistent.
. . . Due to the manpower requirements exceeding our manpower
availability, approximately twenty (20) projects were
awarded to private engineering firms to prepare traffic
engineering plans in 1988.
... Twelve (12) projects have been negotiated and are
awaiting Board of Transportation approval for January and
February 1989 boards for award to private engineering
firms
.
Computer Aided Drafting and Design ( CADD )
:
. . . Our unit completed priority projects on the CADD when
faced with immediate deadlines:
- 1-2204: The Alternate Route Map on the 1-40 project at
Research Triangle Park was designed for the brochures and
posters as part of the public information plan.
- I-2204A: This priority project, Westgate Road/ Aviation
Parkway Intersection at US 70, was digitized and designed
exclusively in this unit on the CADD. This was done as a
"no roadway plan Traffic Control design" with the traffic
control plan and signal plan handled exclusively by
Traffic Engineering.
. . . Plan sheets of 1-2005 were digitized on the CADD to show
the limited sight distance along a curve on westbound I-
240 at Merrimon Street bridge in Asheville. These
drawings revealed that the minimum sight distance was not
met around the curve and it cannot be met at the existing
speed and degree of curve of the facility. By using the
stopped/moving vehicle design model on the CADD, our
calculations were substantiated.
... The Unit began placing roadway standard drawings, traffic
control and pavement marking typicals on the CADD. A
task force has been formed to review the existing
drawings and update them to the existing policies and
standards

estimated annual operating cost savings of $ 14,627,892. Since
the commencement of the Federal Energy Contract Program three
years ago, 1380 intersections have been retimed for an annual
operating cost savings of $ 68,659,870.
SIGNAL EQUIPMENT SQUAD
Activities
:
The Signal Equipment Squad procures, evaluates, stocks and
distributes traffic control equipment. It provides technical
assistance to various agencies and administers railroad signal
construction projects and maintenance payments to railroad
companies for grade crossing maintenance. The squad also
evaluates all equipment proposed by vendors. Additionally, the
squad reviews all traffic signal equipment selected by the
Signals and Geometries Unit to assure that the equipment proposed
can accommodate the developed design. When a special traffic
signal function is required, the squad designs necessary
circuitry and develops schematics to implement the special
function.
During the past year, the squad assisted Division 6 in the
construction phase of the City of Fayetteville computerized
signal system. The system operational testing is scheduled to
begin in early 1989.
Construction of a 47 intersection signal system was begun in
Asheville with all equipment on work site. Construction is being
